Looks like option A

P(AUB) + Neither =P(A) + P(B) - P(A and B)

Now we get 1 + neither =1/4 +3/5 -x

Therefore X+neither =3/20

The question asks which of following option COULD BE the value ..

So anything less than equal to to 3/20 should be right..since if neither is zero or a little more ..it will have a reducing effect on x or 3/20

So option A

Press Kudos if it helps !!

prabsahi bcoz it is an MCQ if event F is a subset of event E then (E and F) = 0.25
so ans should be A and B?
